This is a new gun based on the R91 aka G3 Assault Rifle - the gun that's called Assault Rifle in the game. The differences between this gun and the R91: increased magazine capacity (30, equal to the Xuanlong), single-shot semi-automatic rather than full automatic, reduced spread (0.5 compared to 1.5, equal to the Perforator), reduced reload time, should be slightly increased damage per second, and the AP cost was increased 2 points, to 25.
Thanks for any and all feedback. The weapon can be found leaning against the Washington Monument gates; another copy at less than full condition can be found inside the monument. Naturally, use R91 assault rifles to repair.
The model of the gun is based on the Infiltrator. The scope and silencer have been removed, and the tip from the Lincoln's Repeater was used to cover the original barrel.
